All of the keyboard shortcuts work for me in Preview with PDF files.
Thanks. To add a note, do you simply press the Control, Command, and n keys?

Yep thats all I did. It may be that your file is protected so you cant make changes to it. The files I tested on were just PDF copies of my taxes that I made so maybe thats why I was able to do it.
